Abstract (en)
The method involves injecting two populations of particles into a supersonic nozzle (54) at the same time and entraining both populations of particles in a flow of gas directed through the nozzle. The populations of particles are injected to the nozzle simultaneously wherein one population of particles is thermally softened in the nozzle under the spray parameters and the other population is not. The temperature of gas is selected to be insufficient to heat the first population of particles to a temperature at or above their melting temperature in the nozzle, and the particles are accelerated to a velocity sufficient to result in adherence of particles on the substrate positioned opposite the nozzle. The temperature of gas is selected to be sufficient to heat the second population of particles to a temperature at or above their melting temperature in the nozzle, wherein melting the second population of particles and accelerating the molten particles to a velocity sufficient to results in adherence of particles on the substrate, thus forming a coating on the substrate that is a combination of both populations of particles.
